Næturvaktin

Georg Bjarnfreðarson (Jón Gnarr) is the eccentric nightshift manager at the Shell garage on Laugavegur, the main road through downtown Reykjavík. He is a power-hungry Communist inspired by Soviet ideals, yet still lives at home with his mother (as we find out in Dagvaktin). He claims to have five degrees: psychology, sociology, pedagogy, political science and a teaching qualification. A fan of bureaucracy, he enjoys putting his subordinates through ordeals over trivial matters, such as how to spend the staff holiday fund (staging an official vote inline with the general elections). He also is insistent on the use of walkie talkies, addressing his colleagues as "personnel on the forecourt" (another of his catchphrases). He is unable to accept defeat in the face of any situation, no matter how stupid. He has one son, Flemming Geir, an obese 12-year-old whom he neglects and leaves to steal chocolate from the stockroom.

He is the central focus of the trilogy, and the film Bjarnfreðarson focuses on his upbringing and the reasons for his eccentricity.

Ólafur Ragnar Hannesson (Pétur Jóhann Sigfússon) is the longest-standing employee at the petrol station. He has aspirations of becoming a band manager, and is often trying to organise gigs for his friends' band, Sólin ("The Sun"). The band quickly becomes fed up of his inability to book gigs and complete lack of knowledge of the music industry, and dump him as manager. He becomes the subject of mockery from Georg when he enters the Icelandic X Factor in pursuit of his musical ambitions. Stupid and gullible but well meaning, Ólafur is often on the receiving end of bad situations, becoming involved in advance-fee fraud with a man from Nigeria, and falling foul of a Chinese protein shake which induces lactation. He is submissive and often follows Georg's instructions, no matter how unusual, without question.

Daníel Sævarsson (Jörundur Ragnarsson) is a medical school drop-out who begins working at the petrol station at the beginning of the series. He is shy and introverted, and unsure of what he wants to do with his life. He has anxiety and depression, and has completely cut off all connections with his family. Unlike Ólafur, he recognises the stupidity in Georg's decisions and often challenges him when things seem unfair. His ex-girlfriend and family appear numerous times in the series, attempting to get him to resume his studies and become a doctor like his father and grandfather. He is bright and is often able to humiliate Georg, for example by identifying a man who has recently had a stroke, whom Georg tars as a drunk and assaults. To Georg's annoyance, Daniel is much better at chess than he is, managing to beat him on several occasions. He is susceptible to mood swings and storms out whenever Georg makes him sufficiently angry.

In 2009, the American production company Reveille Productions purchased production rights for a remake for the U.S. market,[2] with the Fox Network purchasing broadcasting rights.[3] Howard Owens, the managing director of Reveille, said:

The Night Shift is that rare international format that has American sensibility, and we're eager to tackle another workplace comedy after the success of The Office [...] The show has a smart, ironic point of view, which we know will translate well in the U.S.[4][5]

In January 2010, the screenplay for the American adaptation was completed by screenwriter Adam Barr. Whether a pilot episode will be made has yet to be decided. Nevertheless, the screenplay includes American adaptations of the characters. Ólafur Ragnar's name has been changed to Tommy, but otherwise his character is the same. The other two main characters have undergone more significant changes, however. The character of Daníel keeps his name and is still a medical school drop-out, but his introverted personality has undergone a complete inversion and – according to Iceland Review – he will be "a hunk playing the field". Georg Bjarnfreðarson's character has undergone a complete transformation, into a survivalist.[6]

On 31 July 2018, ZDFneo started broadcasting a German adaptation called Tanken - mehr als Super.[7]

In Norway, the series was remade under the name Nattskiftet, starring popular Norwegian comedian Otto Jespersen. It was first broadcast in 2012.
